[0083] In some of the processes described in the specification and claims of the present invention and the above-mentioned figures, multiple operations that appear in a specific order are included, but it should be clearly understood that these operations may not be executed in the order in which they appear in this article or executed in parallel. The serial numbers of the operations, such as 101, 102, etc., are only used to distinguish different operations, and the serial numbers themselves do not represent any execution order. In addition, these processes may include more or fewer operations, and these operations may be executed in sequence or in parallel. It should be noted that the descriptions of "first", "second", etc. in this article are used to distinguish different messages, devices, modules, etc., do not represent the order of precedence, and do not limit the "first" and "second" to be different types.

[0084] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative work are within the scope of protection of the present invention.

[0085] The acetate fiber production line includes various raw material storage tanks, filters, storage tanks, degassing tanks, spinning machines, yarn bundling devices, crimping machines, conveyors, multi-channel conveying swing bucket mechanisms, dryers and swing wire machines; the raw material storage tanks, dissolving tanks, filters, storage tanks, degassing tanks are connected to the spinning machines in sequence, and the spinning machines are connected to the crimping machines through the yarn bundling devices; the crimping machines are connected to the multi-channel conveying swing bucket mechanisms; the multi-channel conveying swing bucket mechanisms are connected to the dryers front and back and are located above the dryers; the swing wire machines are connected to the dryers.

[0086] In the prior art, the acetate fiber production line is capable of producing acetate fiber with high efficiency and high quality. Through the reasonable configuration of various equipment, especially the design of the return air device in the tunnel, the yarn bundling device and the multi-channel conveying swing bucket device, various defects that affect the product quality are eliminated, ensuring high-efficiency, stable and reliable production and the quality of the finished yarn. However, in the prior art, if the number of production lines has been determined, it cannot be modified, which greatly limits the production capacity level of the generated products.

[0087] In the embodiment of the present invention, a flexible production method and system for diacetate fiber are provided. The solution provides a flexible production process for acetate fiber, and through the dovetail groove roller layout and the high-speed curved motion laying technology of the tow, the production line is increased to multiple lines, achieving a 50% increase in product capacity in a limited space.

[0088] According to a first aspect of an embodiment of the present invention, a flexible production method for diacetate fiber is provided.

[0089] Figure 1 The present invention is a flowchart of a flexible production method of diacetate fiber according to an embodiment of the present invention.

[0090] In one or more embodiments, preferably, the flexible production method of diacetate fiber includes:

[0091] S101, setting an improved spinning machine structure to adapt to online updating of the number of wires;

[0092] S102, setting a switching process between four-wire and five-wire according to the improved spinning machine structure;

[0093] S103, setting a switching process between four-line and three-line according to the improved spinning machine structure;

[0094] S104, setting a switching process of four lines, five lines and six lines according to the improved spinning machine structure;

[0095] S105, obtaining the line change demand of the current spinning machine, and performing online switching according to the line change demand;

[0096] S106. After the online switching is completed, the system interface after the line change is displayed.

[0097] In the embodiment of the present invention, when performing four-to-five (five-to-six) and four-to-three conversions, it is necessary to replace the Crotti rollers of different widths to adapt to the production of new specifications. The width of the Crotti rollers produced by the five-line and six-line production is 17-20mm, and the width of the Crotti rollers produced by the three-line production is 25-30mm. For this reason, it is necessary to set preset Crotti rollers of different widths in advance to adapt to online replacement.

[0098] Figure 2The present invention is a flowchart of an improved spinning machine structure in a flexible production method of diacetate fiber in one embodiment of the present invention, which is used to adapt to online updating of the number of lines.

[0099] like Figure 2 As shown, in one or more embodiments, preferably, the improved spinning machine structure is configured to adapt to online updating of the number of wires, specifically including:

[0100] S201, under the four-wire system, set each line to have 31-35 corridors;

[0101] S202, under the five-line system, set each line to have 24-28 corridors;

[0102] S203. Under the six-line system, set up 20-24 corridors for each line.

[0103] S204, equip each line with 1-3 thread-repairing guns;

[0104] S205, setting the height of the spinning machine Crotti roller fixing groove to be 1-3 cm lower than the original height;

[0105] S206, setting different widths of Crotti rollers to adapt to the production of new specifications. The width of Crotti rollers produced by the fifth and sixth lines is 17-20 mm, and the width of Crotti rollers produced by the third line is 25-30 mm;

[0106] S207, setting the gap between the climbing rollers of the partitions along the spinning machine to a preset width;

[0107] S208. When setting the climbing rollers at the air suction port of the spinning machine, one more set of rollers is required when the number of rollers is changed from four to five, and another set of rollers is required when the number of rollers is changed from five to six. The dovetail groove uses a 12-15 groove mode, and 1-3 climbing rollers used on the same line are installed with an interval of 1-3 grooves.

[0108] In the embodiment of the present invention, in order to adapt to the control of the flexible production of the current spinning machine, the setting and adjustment of the spinning machine are described. The specific explanation is as follows: First, under the four-line system, each line has 31-35 corridors; under the five-line system, each line has 24-28 corridors; under the six-line system, each line has 20-24 corridors. This is a different configuration mode of the spinning machine, and the appropriate line system is selected according to production requirements. Secondly, each line is equipped with 1-3 wire supplement guns. This is a device used to supplement the silk thread on the spinning machine. Furthermore, the height of the fixed groove of the spinning machine Crotti roller is set to be reduced by 1-3cm. This is to adjust a component on the spinning machine to adapt to the new production specifications. On this basis, different widths of Crotti rollers are set to adapt to the production of new specifications. The width of the Crotti rollers produced by five and six lines is 17-20mm, and the width of the Crotti rollers produced by three lines is 25-30mm. This is to adjust another component on the spinning machine to adapt to the switching between different production methods; and then the gap between the climbing rollers on the partitions along the spinning machine is set to a preset width. This is to adjust a component on the spinning machine to meet production requirements. When the climbing rollers at the suction port of the spinning machine are changed from four to five, one more set of rollers needs to be added, and when the climbing rollers are changed from five to six, one more set of rollers needs to be added. The dovetail groove uses a 12-15 groove mode, and 1-3 climbing rollers used on the same line are installed with an interval of 1-3 grooves. This is to adjust a component on the spinning machine to meet the conversion needs between different line systems.

[0109] Figure 3 It is a flow chart of a switching process of setting four-wire and five-wire according to the improved spinning machine structure in a flexible production method of diacetate fiber according to one embodiment of the present invention.

[0110] like Figure 3 As shown, in one or more embodiments, preferably, the switching process of setting four-wire and five-wire according to the improved spinning machine structure specifically includes:

[0112] S302, after clicking the spinning machine selection button, a dialog box pops up to select the current mode as one of the four-wire system and the five-wire system;

[0113] S303, when in the four-wire / five-wire system state, the button corresponding to the current four-wire / five-wire system is in an unselectable state;

[0114] S304, if the switchable line state is clicked, a secondary confirmation box pops up to determine whether it is an erroneous operation. If it is not an erroneous operation, the line switching continues. If it is an erroneous operation, no processing is performed;

[0115] S305, when starting the wire system switching, judging whether the switching task meets the first preset condition, wherein the first preset condition includes switching the unused wire filling box to the parking state before switching from the 5-wire system to the 4-wire system to prevent it from having additional meaningless alarms, and when switching from the 5-wire system to the 4-wire system, one of the wire filling guns in the 5-wire system is not used;

[0116] S306, under the 4-wire system, the No. 2 wire filling box is not put into use, and the relevant wire break alarm information is displayed;

[0117] S307. Under the 5-wire system, 5 wire filling boxes are put into use, and 27-30 channels are set for each line.

[0120] S401, setting the control interface of the spinning machine to at least include a four-line mode and a three-line mode;

[0121] S402, after clicking the spinning machine selection button, a dialog box pops up to select the current mode as a four-wire system or a three-wire system;

[0122] S403, when in the four-wire / three-wire state, the button corresponding to the current four-wire / three-wire state is in an unselectable state;

[0123] S404, if the switchable line state is clicked, a secondary confirmation box pops up to determine whether it is an erroneous operation. If it is not an erroneous operation, the line switching continues. If it is an erroneous operation, no processing is performed;

[0124] S405, when starting the wire system switching, determining whether the switching task meets the second preset condition, wherein the second preset condition includes switching the soon-to-be-unused wire filling box to the parking state before switching the four-wire system to the three-wire system;

[0125] S406, under the three-wire system, the No. 2 wire mending box is not put into use, each line has 46-50 channels, wire mending is performed for each line, and the wire break alarm information is displayed;

[0126] S407, under the four-wire system, four wire filling boxes are put into use, and each line has 34-38 channels.

[0127] Figure 5It is a flow chart of a switching process of setting four-wire, five-wire and six-wire according to the improved spinning machine structure in a flexible production method of diacetate fiber in one embodiment of the present invention.

[0128] like Figure 5 As shown, in one or more embodiments, preferably, the switching process of setting four lines, five lines and six lines according to the improved spinning machine structure specifically includes:

[0129] S501, setting the control interface of the spinning machine to at least include a four-wire mode, a five-wire mode and a six-wire mode;

[0130] S502, after clicking the spinning machine selection button, a dialog box pops up to select the current mode as one of the four-wire system, the five-wire system or the six-wire system;

[0131] S503, when in the four-wire system, five-wire system or six-wire system state, the button corresponding to the current four-wire system, five-wire system or six-wire system is in an unselectable state;

[0132] S504, if the switchable line state is clicked, a secondary confirmation box pops up to determine whether it is an erroneous operation. If it is not an erroneous operation, the line switching continues. If it is an erroneous operation, no processing is performed;

[0133] S505. When starting the wire system switching, determine whether the switching task meets the third preset condition, and the third preset condition includes that before switching to the four-wire system, two of the wire-repairing boxes must be switched to the parking state, and before switching to the five-wire system, one of the wire-repairing boxes must be switched to the parking state.

[0134] Figure 6 It is a flowchart of obtaining the current line change demand of a spinning machine in a flexible production method of diacetate fiber in one embodiment of the present invention and performing online switching according to the line change demand.

[0135] like Figure 6 As shown, in one or more embodiments, preferably, the obtaining of the current line change demand of the spinning machine and performing online switching according to the line change demand specifically includes:

[0136] S601, obtaining the current line change demand online, determining whether it is a switch of four lines, five lines or six lines, and switching to the preset first screen;

[0137] S602, determining whether the current line change demand is a switch between four lines and five lines, if it is a switch to a preset second screen;

[0138] S603, determining whether the current line change demand is a switch between four lines and three lines, if it is a switch to a preset third screen.

[0139] In an embodiment of the present invention, the implementation steps include obtaining the current line change demand online, judging whether it belongs to the switching of four lines, five lines and six lines, and switching to the preset first screen; then further judging whether it belongs to the switching of four lines and five lines or the switching of four lines and three lines according to the specific needs, and switching to the preset second screen or third screen respectively. The line system of the spinning machine (such as four lines, five lines and six lines) directly affects the production capacity and product diversity. Therefore, it is of great significance to meet market demand to be able to quickly and accurately switch the line system configuration of the production line. The specific process includes: determining the line change demand: first, the current line change demand needs to be input through the system interface or console. This step is usually completed by the operator according to the needs of the production plan. The system needs to be able to identify different line system requirements, such as four lines, five lines or six lines, and automatically perform preliminary screen switching according to these requirements. Switching screen: After confirming that the line system needs to be switched, the system first switches to a preset basic screen, which usually contains all the basic settings and parameters of the line systems that may be involved. Refine the specific switch: If it is confirmed that it is a switch between four lines and five lines, the system will switch to another preset screen, which is specially configured for the specific needs of these two lines. Handle special switch: If it is a special switch between four lines and three lines, it is necessary to switch to another special screen for processing. This kind of switch is relatively rare and usually involves greater structural adjustments and parameter changes. Confirm that the adjustment is completed: After each screen switch and parameter adjustment, it is necessary to verify whether the new configuration is correct through the system's test function to ensure that the production line can run smoothly.

[0140] Figure 7 It is a flow chart of the system interface display after the line is changed after the online switching is completed in a flexible production method of diacetate fiber according to an embodiment of the present invention.

[0141] like Figure 7 As shown, in one or more embodiments, preferably, after completing the online switching, the system interface display after the line change specifically includes:
